SAN FRANCISCO — Federal attorneys have charged a woman with robbing five Bay Area banks from January through June.

Yolanda Brown, whom federal authorities say goes by the alias “Yo-Yo,” faces 20 years in prison for each count of robbing banks in San Francisco, San Leandro and Antioch. She has also been charged with felony gun possession in an indictment handed down last week.

An Antioch city manager’s report from June suggests that authorities had linked a Wells Fargo robbery there on the 3300 block of Deer Valley Road to other robberies in San Francisco. The June 16 report says the Wells Fargo was robbed around 10 a.m. by a woman who told the teller her intentions and fled the area on foot.

A week earlier, on June 9, Brown allegedly robbed a Citibank on the 2400 block of 19th Street in San Francisco. After robbing a Wells Fargo in San Francisco on Jan. 11, authorities say she hit the same Patelco Credit Union in San Leandro on consecutive months; once on Jan. 13, and once on Feb. 19.

Authorities say a semi-automatic pistol with a partially obliterated serial number was later found in her possession.

Brown remains in custody, according to court documents, but her bail amount has not been posted. She has not yet entered a plea.

Questionable special-interest provisions have been stuffed in along the way, out of public view and in some cases literally in the dead of night. Drafting errors by exhausted staff are cropping up in need of fixes, which must be tackled by congressional negotiators working to reconcile competing versions of the legislation passed separately by the House and the Senate.
